Overview
The MAX1070CTC+ is a high-performance, low-power, 10-bit analog-to-digital converter (ADC) produced by Analog Devices Inc./Maxim Integrated. This device operates from a single supply voltage ranging from +2.7V to +3.6V and requires an external reference voltage. The MAX1070CTC+ features true-differential inputs, which provide better noise immunity, distortion improvements, and a wider dynamic range compared to single-ended inputs. It is designed for high-speed applications, supporting conversion rates up to 1.5 million samples per second (Msps).
